Y IMPRVEMENT IN DETACHABL FLUID-RESERVOIRS FOR STREET-'LAMPS'.

The Schedule referred to in these Letters Patent and making part o the same.

To all wh'o'm 'it may conce/rn:

Be it known that I, LYMAN A. GOUGH, of Yonkers, in the county of ,Westchester and State of New York, have invented a new and useful Detachable Fluid- Reservoir for Streep-Lamps; and I do hereby declare that the following is a full, clear, and exact description thereof, reference beingA had to the accompanying drawing forming a part of this specification.

This invention relates more particularly to streetlamps in which uapbtha is burned, but it is also applicable to any other fluid-burning lamp.

1t consists in a detachable Huid-reservoir which surrounds the exterior oi' the head of the lamp and rests ou the shoulder thereof, and has attached to it the tube which carries the burner of the lamp.

By makingA this outside reservoir detachable, facilty is alorded for painting all parts ci' it, and of the lamp-frame, which cannot be conveniently done when such reservoir is a fixture. Facility is also aiorded for' repairing it in case of leakage, and the reservoirs of all the lamps in a district may be collected and taken away to a depot to be filled.

In the accompanying drawing- Figure l is a central vertical section of alamp made according to my invention, and

Figure 2 is a perspective- View of the Huid-reservoir detached from the lamp.

Similar letters of reference indicate corresponding parts in both figures.

A is the reservoir, made ot`- tin-plate or sheet metal, and of the same shape in its horizontal section as the horizontal section gf the lamp B.

t is circular in its transverse section, and provided v on its upper side with a feed-opening, c, fitted with a suit-.able stopper.

The reservoir is ornamented on its outer side with a downwardly-projecting serrated strip of metal, b.

Extending downwardly-troni one corner of thereservor is a tube or pipe, g, which is inserted' through a hole in the upper palt of the lamp, and is bent at the lower end to provide for the attachment of the lam p-burner. .A

This reservoir surrounds the head of the lamp and rests on the shoulders a thereof, being kept in place behind the springs s s.

vthrough the frame by turning them {edgewise and by fitting around the head and shoulder. It is easily 4removed by raising it a little, then turning it to a position to pennitthe withdrawal of the' pipe, and after ward lifting it oli.

O C are the side glasses of the lamp, the lower edges of which are secured in grooves f f-in the bot torn of the frame of the lamp, and their upper edges are held by springs s s, secured to tbc shoulder a of the lamp. A

These glasses can be removed by simply first lifting their lower edges out ofthe grooves -in the frame of the' lamp, and then drawing their upper edges from 'lhey may 'then be removed drawing them out.

To reiusert the glasses they are first inserted within the lamp and theirupper edges are slid behind the springs s s, and their lower edges are dropped into the grooves l f f, and they are thereby secured.

The bottom glass G simply rests on the bottom of the frame, and may be removed by turning it diagonally acrossthe hole therein alld drawing it ont.

This method of securing the glass provides for its expansion and obviates the danger of breaking by that means.

The pipe g, to which the burner is attached, may be provided with a cock to stop the supply of Huid to the burner when the lamp is not in use; but the burner Witnesses Feen. HAYNEs, B.. E. RABEAU.
